While I wouldn't want to say that I know what Macnfries was intending, but I would think that if a guy is on here with his girl or wife looking for her to enjoy some BBC, the sex issue is not so much one of being lousy in bed, but more one of adding to her pleasure or obtaining that which he can't completely provide, which in a way is him taking care of her sexual needs and desires.
So in that context, taking care of all the other things a good marriage or relationship requires is what is most important for those of us who have that mind set as the sex is something that is taking care of itself.
